Yarok, the Desecrated + doubling season

Asked by YearlingElf0681 2 years ago

Me and my roommate are wondering again, what would happen In his deck. At this point we want to add Yarok, the Desecrated and have many things trigger over and over again ,such as Doubling Season . Other interactions in the deck to make it trigger over and over again is Rings of Brighthearth , Strionic Resonator , ECT ECT and we are trying to figure out if Yarok's effect will work on doubling season and a few other cards like it

This has potential for interesting interactions, particularly with the Doubling season + Brighthearth combo. It can get complicated, but here's my crack at it.

Yarok's ability can only trigger when a permanent enters the battlefield, so you'll you can't trigger it multiple times unless you have ways to create more permanents. Similarly with Strionic Resonator, you have to tap it to copy any ability, so you'll only be able to use it once unless you can untap it somehow.

As for Rings of Brighthearth and Doubling season, you can activate these abilites at any time, and as long as you have enough mana in the case of the Rings. Lets say, for example, that some permanent enters the battlefield, which causes us to create a single token. Doubling season activates, giving us another - a total of 2 so far. Yarok's ability will activate as well, making one more, copying the original token. Of course, this will also be doubled by Doubling season, so we're up to 4 now. You could then activate the Rings, copying the either use of Doubling Season's ability, allowing you to target either of the original uses of Doubling Season's ability. The original uses each only made 1 additional token, so pick one and it will make 2 instead. Of course, this is doubled again, which you can choose to copy again, which will be doubled again, and so on. In total, if you choose optimal targets and target the most recent double from Doubling Season, you'll end up with 3 + 1*4^X tokens, where X is the number of times you've spent 2 mana to copy an ability with Rings of Brighthearth. 1 from the original token, 1 more that was copied by Yarok, 1 more because we doubled Yarok's ability with Doubling Season, then the rest from redoubing the other instance of Doubling Season's ability as many times as possible.

It's quite possible I messed something up in this calculation. Let me know if you have any other questions, or if this is confusing, or if you think I made a mistake somewhere!

Note: Definitely some typos in my above post, though I think I still have correct points there.

Sinq_'s post has a number of inaccuracies, so I wanted to provide a more clear response.

The biggest problem with Sinq_'s post comes from their incorrectly categorizing various effects as triggered abilities, when, in fact, the OP references three distinct effects--triggered abilities, activated abilities, and replacement effects.

Let's break down the three different types of ability referenced in the OP.

A replacement effect modifies how an in-game event occurs--they do not "trigger" and do not use the stack; they simply change how the rules work with regards to whatever it is they are replacing. (See Rule 614) These effects will use the words "instead" and "if" to indicate they are a replacement effect. Yarok, the Desecrated 's ability is a Replacement Effect--it changes how ETB triggered ability functions so, instead of getting one instance of the ability, you get two of them. Doubling season is also a replacement effect--instead of getting X counters, you get 2X counters; and instead of getting Y tokens, you get 2Y tokens.

A triggered ability is triggered by a defined event, placing the ability on the stack. The ability must resolve before any effect occurs. (See Rule 603). A triggered ability will use the words "when", "whenever", or "at" followed by the triggering event, followed by the effect that will occur on resolution.

An activated ability is an ability which must be activated by paying a cost. (See Rule 602) It will always have a cost, followed by a colon, followed by the effect that happens on resolution.


Yarok only adds an additional instance of triggered abilities. It will not add any additional instances of any replacement effects. As such, Yarok does not interact with Doubling Season .

For the same reason, neither Doubling Season nor Yarok can be copied by Strionic Resonator --Resonator only can copy triggered abilities, and these are both replacement effects. Resonator can copy whatever triggered ability is being replaced with two triggered abilities. So, if you have Basalt Ravager enter the battlefield, you would get two triggers of its ability due to Yarok, then could use Resonator to copy one of those triggers, netting you three triggers on the stack.

Rings of Brighthearth has no direct interaction with Yarok or Doubling season, as they are both replacement effects. Further, Rings has no direct interaction with whatever triggered abilities Yarok replaces, as Rings copies activated abilities, and Yarok increases the number of triggered abilities.

The only real interaction you have of the cards listed in the OP is between Rings and Resonator.

Rings is a triggered ability--the trigger is an activated ability being activated. Upon resolution of the Rings Trigger, you can pay mana to add another copy of the underlying activated ability.

Resonator is an activated ability that can target a triggered ability.

So, here is where they intersect:

  1. When a something triggers an ability, you can activate Resonator and put Resonator's ability on the stack.

  2. Rings will trigger due to the activation of Resonator.

  3. Rings resolves, and you get another instance of Resonator put on the stack. You can choose a new triggered ability to copy. Hypothetically you could target the same Rings ability that is in the process of resolving... but that would be silly. By the time the Resonator ability resolves, there would be no Rings trigger to copy, so the copy effect would fail due to lack of valid target.

  4. So, with a single creature ETBing, your Yarok will result in two triggers, your Resonator's ability will result in one copy, and your Rings' copy of Resonator will result in a second copy, resulting in 4 copies of the ETB triggered ability being on the stack.

Doubling Season , Rings of Brighthearth , Yarok, the Desecrated , and Strionic Resonator don't really interact with eachother. The only interactions are between Rings of Brighthearth and Strionic Resonator .

If have a triggered ability, you can activate Strionic Resonator to copy it, which will trigger Rings of Brighthearth , letting you pay to copy it twice instead of to copy it once.

If you activate an ability, Rings of Brighthearth will trigger and Strionic Resonator can be activated targeting it's trigger. This interaction allows you to pay to copy an activated ability twice instead of to copy it once. Since I already mentioned Rings can copy the activation, you can also pay to copy it thrice.


Since these cards do interact with other pieces, I'm going to address the main cases of permanents entering with Doubling Season .

If you have something like Ambassador Oak enter the battlefield, Yarok can make it trigger twice, giving you two 1/1 elves. Strionic Resonator can be activated to copy the trigger to give you an additional elf. Doubling Season will double all elves created, regardless of how many triggers you have. Rings of Brighthearth doesn't trigger here except for it's interaction with Strionic Resonator .

Another guess would be if you want to play something with counters, like Scrounging Bandar . Doubling Season will double the counters it enters with. Yarok has no interaction because there's no triggered ability (triggered abilities start with when, whenever, or at). Similarly Strionic Resonator cannot be used. Rings of Brighthearth also doesn't do anything.

If you have a copy of Grizzly Bears resolve (due to Reflections of Littjara having chosen Bear) it enters as a token. This is not creating a token so it has no interaction with Doubling Season . It doesn't trigger anything when it enters, so Yarok does not interact. You can target the cast trigger from Reflections of Littjara with Strionic Resonator to create a second copy of the spell though, so you end up with two token Grizzly Bears in addition to the nontoken one. Rings of Brighthearth has no additional functionality beyond it's interaction with Strionic Resonator .
